Previous studies have identified that indole-oxidases are present in P. putida, whose major ligands are heterocyclic substrates and have an interesting affinity when the substrate is indole. 19005-93-7, formula is C9H7NO, Name is 1H-Indole-2-carbaldehyde. These enzymes oxidize the ring so the substrate turns into Indigo. Reference of 19005-93-7.

ST4 produces variety of active compounds to interfere fungal sexual mating and hyphal growth》, the research content is summarized as follows. Sexual mating of compatible sporida is essential for Sporisorium scitamineum to form dikaryotic mycelia and then cause infection on sugarcane. Our previous work identified a Pseudomonas sp. ST4 from a soil sample, which showed a promising biocontrol potential by inhibiting the mating of S. scitamineum sporida and hyphal growth. In this study, we set to isolate the active compounds from Pseudomonas sp. ST4 through solid fermentation High-performance liquid chromatog. (HPLC) separation coupling with bioassay showed that Pseudomonas sp. ST4 produced a range of antimicrobial compounds Two of the major components were purified following acetate extraction, silica gel and HPLC separation NMR (NMR) and liquid chromatog.-mass spectrometry (LC-MS) anal. identified these active compounds are 4-hydroxybenzaldehyde and indole-3-carbaldehyde resp. Further anal. showed that the former compound only inhibited the hyphal growth of the fungus at a concentration of 3 mM, while the latter interfered the fungal sexual mating at a concentration of 0.6 mM and affected hyphal growth at a concentration of 2 mM. Treatment of corn plants with 3 mM indole-3-carbaldehyde significantly inhibited corn smut infection, with a control rate up to 94%. Further anal. of the structure and activity relationship revealed that indole has a much stronger inhibitory activity against the fungal sexual mating than indole-3-carbaldehyde. The results from this study provide new agents for control and prevention of the sugarcane smut disease, and the active compounds could also be used to probe the mol. mechanisms of fungal sexual mating.
